pvfs_open, and handle the various race conditions that are inherent in

preparation for the full share modes and ntcreatex code that I am
working on.
highlights include:
- changed the way a backend determines if it is allowed to process a
request asynchronously. The previous method of looking at the
send_fn caused problems when an intermediate ntvfs module disabled
it, and the caller then wanted to finished processing using this
function. The new method is a REQ_CONTROL_MAY_ASYNC flag in
req->control_flags, which is also a bit easier to read
- fixed 2 bugs in the readbraw server code. One related to trying to
answer a readbraw with smb signing (which can't work, and crashed
our signing code), the second related to error handling, which
attempted to send a normal SMB error packet, when readbraw must
send a 0 read reply (as it has no header)
- added several more ntvfs_generic.c generic mapping functions. This
means that backends no longer need to implement such esoteric
functions as SMBwriteunlock() if they don't want to. The backend
can just request the mapping layer turn it into a write followed by
an unlock. This makes the backends considerably simpler as they
only need to implement one style of each function for lock, read,
write, open etc, rather than the full host of functions that SMB
provides. A backend can still choose to implement them
individually, of course, and the CIFS backend does that.
- simplified the generic structures to make them identical to the
principal call for several common SMB calls (such as
RAW_WRITE_GENERIC now being an alias for RAW_WRITE_WRITEX).
- started rewriting the pvfs_open() code in preparation for the full
ntcreatex semantics.
- in pvfs_open and ipc_open, initially allocate the open file
structure as a child of the request, so on error we don't need to
clean up. Then when we are going to succeed the open steal the
pointer into the long term backend context. This makes for much
simpler error handling (and fixes some bugs)
- use a destructor in the ipc backend to make sure that everthing is
cleaned up on receive error conditions.
- switched the ipc backend to using idtree for fnum allocation
- in the ntvfs_generic mapping routines, use a allocated secondary
structure not a stack structure to ensure the request pointer
remains valid even if the backend replies async.

idr_get_new() limits
- change idr_get_new() to use > instead of >= in the limit check

an extremely efficient way of mapping from an integer handle (such as
an open file handle) to a pointer (such as the structure containing
the open file information). The code is taken from lib/idr.c in the
2.6 Linux kernel, and is very fast and space efficient. By using
talloc it even has auto cleanup.
This commit converts the handling of open file handles and open
directory search handles to use the idtree routines. In combination
with talloc destructors, this simplifies the structure handling in the
pvfs backend a lot. For example, we no longer need to keep a linked
list of open directory searches at all, and we no longer need to do
linear scans of the list of open files on most operations.
The end result is that the pvfs code is now extremely scalable. You
can have 10s of thousands of open files and open searches and the code
still runs very fast.
I have also added a small optimisation into the file close path, to
avoid looking in the byte range locking database if we know that there
are no locks outstanding.

messaging_deregister()
- added a pvfs_lock_close_pending() hook to remove pending locks on file close
- fixed the private ptr argument to messaging_deregister() in pvfs_wait
- fixed a bug in continuing lock requests after a lock that is blocking a pending lock is removed
- removed bogus brl_unlock() call in lock continue
- corrected error code for LOCKING_ANDX_CHANGE_LOCKTYPE
- expanded the lock cancel test suite to test lock cancel by unlock and by close
- added a testsuite for LOCKING_ANDX_CHANGE_LOCKTYPE

an early lock timeout
added support for more of the bizarre special lock offset semantics of w2k3
(This used to be commit d5bfc910b1200fb283e26572dc57fcf93652fd32)

This adds a pvfs_wait_message() routine which uses the new messaging
system, event timers and talloc destructors to give a nice generic
async event handling system with a easy to use interface. The
extensions to pvfs_lock.c are based on calls to pvfs_wait_message()
routines.
We now pass all of our smbtorture locking tests, although while
writing this code I have thought of some additonal tests that should
be added, particularly for lock cancel operations. I'll work on that
soon.
This commit also extends the smbtorture lock tests to test the rather
weird 0xEEFFFFFF locking semantics that I have discovered in
win2003. Win2003 treats the 0xEEFFFFFF boundary as special, and will
give different error codes on either side of it. Locks on both sides
are allowed, the only difference is which error code is given when a
lock is denied. Anyone like to hazard a guess as to why? It has
me stumped.

- the stacking of modules
- finding the modules private data
- hide the ntvfs details from the calling layer
- I set NTVFS_INTERFACE_VERSION 0 till we are closer to release
(because we need to solve some async problems with the module stacking)

rather than manual reference counts
- properly support SMBexit in the cifs and posix backends
- added a logoff method to all backends
With these changes the RAW-CONTEXT test now passes against the posix backend

on abnormal termination of a connection. As long as the top level
connection structure is freed then that should cascade down to the
file structure, and call this destructor which will close the open file descriptor.
In general I'd like to use this technique in any place in Samba4 where
we hold operating system resources that we need to make sure are
released on abnormal termination.

something like:
ntvfs handler = nbench posix
and the nbench pass-thru module will be called before the posix
module. The chaining logic is now much saner, and less racy, with each
level in the chain getting its own private pointer rather than relying
on save/restore logic in the pass-thru module.
The only pass-thru module we have at the moment is the nbench one
(which records all traffic in a nbench compatibe format), but I plan
on soon writing a "unixuid" pass-thru module that will implement the
setegid()/setgroups()/seteuid() logic for standard posix uid
handling. This separation of the posix backend from the uid handling
should simplify the code, and make development easier.
I also modified the nbench module so it can do multiple chaining, so
if you want to you can do:
ntvfs module = nbench nbench posix
and it will save 2 copies of the log file in /tmp. This is really only
useful for testing at the moment until we have more than one pass-thru
module.

this is still just a skeleton, and many of the functions are just
based on the simple vfs backend, they are there to allow me to run
smbtorture tests against the real parts of the posix backend.
